Chapter 8 Mayuna, when you're studying and preparing for exams, please let me keep your underwear. ※Note

Erotic scenes

Wow! That’s amazing! I can’t believe there’s a room like that!

She screamed excitedly as she reached for the SM toys.

She touched the small vibrating egg, then the penis-shaped massage stick, and then the hemp rope, her cheeks slightly flushed.

Her cunning demeanor towards SM products makes one wonder where Mayuna, who was originally an excellent student, has gone.

This is also thanks to our regular sex life. We intertwine our bodies every night, allowing her mind, body, and her female nature to grow together.

She seemed completely oblivious to the table, instead reaching for the SM toys, imagining herself being played with. Her legs were trembling slightly.

”Ah…no…I can’t even imagine something like this…”

”Don’t let your breathing become disordered!! You’ll become lewd no matter where you are!!”

”Aaaaaah!!!”

I unexpectedly touched the crotch area of ​​her underwear, causing her body to tremble.

While she wasn’t looking, I reached out from behind and firmly grasped the inside of her labia majora with my index and middle fingers.

The mucus dripped onto her underwear, and her whole body convulsed.

“I’m already soaked… If I walk up to Yurina like this, she’ll probably notice.”

”Ah… just like this… I’m already feeling it… my pussy is so itchy and uncomfortable!”

”You’re a hopeless pervert. You should be focusing on your exams now, not thinking about lewd things, right? I’ll keep these underwear for you.”

”No!!! No, don’t say such terrible things!!! Yurina will find out!!!”

Although she said this while her legs were trembling, it wasn’t convincing at all. I actually think she wanted me to take off her underwear!

I grinned maliciously, reached under her skirt, and pulled off her underwear in one swift motion.

”No way—!!!!”

The layers of bare walls were soaked with love fluid, and when I touched them lightly with my fingertips, the love fluid dripped onto the floor.

Shame and excitement made her legs tremble uncontrollably, and against Mayuna’s will, her body twisted wantonly.

”Mayuna… Haahaha… I’m so excited… Haahaha…”

I stroked her buttocks and anus alternately, trying to suppress the growing excitement in my heart.

Mayuna stared blankly at her exposed lower body, her whole body trembling uncontrollably.

……………………

Mayuna, who was helping me move the table, had sweat dripping down her cheeks as she proceeded cautiously.

When placing the table, she tried to keep her waist straight so that Yurina couldn’t see it. If she was too low, her skirt would flutter, and her buttocks might be visible.

”Then… let’s start by teaching Mandarin…”

Mayuna let Yurina sit on the right and herself on the left, while I stood and taught the two of them.

They looked very nervous as they flipped through their Mandarin textbooks.

Mayuna, who wasn’t wearing underwear, was naturally nervous, while Yurina felt resistant towards me. It was easy to see that her mind was filled with negative thoughts.

”The foundation of the national language lies in reading. Let’s learn Chinese characters.”

Although this time of year isn’t ideal for exam preparation, things have become quite interesting, so I’ll just enjoy it.

I went back to the table, opened the drawer, took out the Chinese character test paper, and placed it on Yurina’s desk.

”The scope of this ability test is all included in this test paper. Although it is impossible to test everything, as long as you can get full marks, you should be able to get close to 30 points.”

”Even so… I still failed…”

”The questions on the Japanese language exam are all solvable if you’ve read the textbook. You don’t need to worry so much… Yurina’s Japanese language grades aren’t bad.”

She has no subjects she excels at, nor subjects she doesn’t excel at; she’s just emotionally vulnerable.

Yurina scoring 50-60 points is quite excellent, isn’t it? Although she herself feels she has let me down, I am very satisfied.

However, if you have a gifted older sister like Mayuna, it’s perhaps inevitable that you’ll underestimate your own abilities.

It’s understandable that someone in the family who consistently scores above 95 might lose confidence.

I shifted my gaze from Yurina to Mayuna, who was looking down.

Although Yurina can’t see it from her angle, she’s not wearing underwear right now, and her female instincts are only half-awake, so she probably can’t concentrate on her studies at all.

The fear of being discovered only fueled their excitement.

Sweat beaded on her forehead and cheeks; she was in a state of confusion, unsure of what to do.

Mayuna’s expression has become so lewd… Is it really that enjoyable? In that case… enjoy it to the fullest in front of Yurina!!

”What’s wrong, Mayuna? You don’t look well.”

I gave Mayuna a sly smile and patted her on the shoulder.

She trembled slightly at first, then looked at me with cloudy eyes. Her trembling lips seemed to want to say something.

”Oh? Is your sister feeling unwell?”

”Waaah…”

That was close! She wasn’t even looking at Yurina, was she?

If Yurina doesn’t speak to her, what is she planning to say?

Please insert your super-sized penis into my vagina?

You really have a lot of shortcomings. If you weren’t my daughter, I would have sent you to work in a brothel to make money long ago.

”No, no, it doesn’t look like that… does it?”

”Hmm, it looks like it. Sister, it’s just family here, so it’s okay.”

”It’s okay…no…”

I lifted Yurina’s skirt where she couldn’t see me.

Mayuna’s buttocks were pressed tightly against the seat of the chair, looking quite ridiculous. She must have felt ashamed.

Of course, I wasn’t just going to watch. To make her even more upset, I pinched her buttocks with my fingers and boldly rubbed her cleft up and down.

The sweaty flesh of my buttocks felt wonderful to the touch, and there was a hot, hard object inside my pants. It kept pushing against me in the cramped space, making me feel even more uncomfortable.

”You really aren’t feeling well, are you?”

”No, no, no… I’m fine… huff… huff… Yurina, you don’t need to worry… huff… huff… huff… It’s okay.”

”You’re breathing very rapidly. You’re just putting on a brave face, aren’t you?”

”You’re so annoying!!! I’m really fine!!!”

Yurina is so kind~ She really likes Mayuna and values ​​her a lot~ For Mayuna, who wants to hide her feelings, Yurina is a troublesome rival~

I gave a malicious smile and gently inserted my finger into her anus.

”Eeee!!!”

Her back straightened instantly, and her lower body trembled uncontrollably.

”Let’s go to the hospital…”

”Yurina!!! You…you want to study, don’t you? Hurry up and go to study as your father…instructed!!!”

Mayuna seemed to be nearing her limit, her eyes bloodshot.

Mayuna shouted, and Yurina’s body trembled. She glanced worriedly at Mayuna’s face while picking up her mechanical pencil.

I turned my gaze to Yurina, who was focused on studying for her exam, and brought my face close to Mayuna’s ear.

”You’re so good at holding back…”

”Yes, yes… because I don’t want to get scolded by Dad… umm… ha…”

Mayuna exhaled a warm breath and comfortably squinted her eyes. I gently stroked her head.

My fingers continued to rub up and down the cleft of her beautiful buttocks; I wouldn’t stop until she finished reading.
